ROLLER-SKATE.

Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed January 2 8, 1915. Serial No. 4,913.

T 0 all whom it may concern Be it known that I, FRANK E. BROWN, a citizen of the United States, residing at Webster City, in the county of Hamilton and State of Iowa, have invented certain new and useful Improvements in Roller- Skates, of which the following is a speci fication.

An object of my invention is to provide a skate which has the front and back rolls thereof arranged to be extensible, and has a securing structure to hold the adjustable members connected in a manner that while relative movement of the parts is permitted in the adjustment, the parts are secured in an absolutely rigid andimmovable relation and against accidental readjustment in use.

A further object is to construct the steering structure of the extension and the parts thereof entirely of sheet metal with the exception of the clamping bolts and to so arrange the members of the same that an interfitting and telescoping connection is formed in which one portion of the structure embraces the remaining portions and in which spreading of the securing structure is prevented.

Yet another object is to provide a skate which is equally well adapted to use of straps as a'means of securing" the same to the foot, as to a full clamp fastening or a combination of the same.

With other objects in view, which will be referred to, my invention consists in the novel features of construction and combination of parts which will be hereinafter more fully set forth in connection with the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings: Figure 1 is a view in side elevation of a form of my improved skate having a clamp fastening for the sole and a strap fastening secured to the heel plate. Fig. 2 is a top plan view of the disclosure in Fig. 1. Fig. 3 is a transverse vertical sectional view taken on the line 3-3 of Fig. 1 to better illustrate the securing or clamping means of the adjustment mechanism.

The wheel trucks or carriages 1 and 2 are of the standard form and design and are pivotally mounted by the pins 3 and a and provided with the rubber cushion blocks to permit side swinging of the forward and rear axles 5 and 6 respectively, to allow the toe member 8 and the heel member 9.

r A toe plate 10 is secured. to the toe member 8 by having slots formed therethrough and the tongues 11 of the side pieces 12 of the toe member pass through these slots and are riveted over, and a heel plate 18 is secured by the rivets 14, or in any other desired manner, to the side plates 15 of the heel member 9to be disposed in a substantially parallel plane with the toe plate 10. The side plates 12 of the toe member 8 are extended to form the'elongated extension bars. 16, and similar elongated extension bars'17 are provided toextend forwardly from the side plates 15 of the heel member 9. Upturned flanges 18 and 19 are provided on the lower edges of the extension bars 16 and 17 respectively, and bars 17 are spaced apart to be received between the bars 16 and to have the flanges 19 thereof bear against the lower faces of the flanges 18, this structure being better illustrated in Fig. 3.

Pins 20 are carried by the extension bars 17 to project from the inner faces thereof and to come to an abutting relation at their inner ends to prevent springing of the extension portion 17{ from the position of bearing against the inner faces of the extension bars 16, and a securing clip 21,

which comprises a top having side flanges 22 is made of a transverse dimension that the side flanges will fit closely over the extension bars 16 to hold these bars in the proper relation. A clamp bolt 23 is received through an orifice 24 in the top of the clip 21 and passes down between the extension bars 17 where a clamp washer 25 is fitted over the ends to bear against the flanges 19 of the extension bars 17, a nut 26 being received on the screw-threaded end of the bolt'23 to clamp the clip 21 against the top edges of the extension bars-16 and the washer 25 against the lower sides of bars 17 to cause the flanges 18 and 19 to be brought to'a frictional bearing and to prevent end movement of the extension members 16 with respect to the members 17. Pins 27 are mounted to project fromthe outerfaces of the extension bars16 to limit movement of these bars with respect to the clip 21, and it will be noted that the abutjusted to bring the forward axle 5 to the with a ment of the pins 20 against thebolt' 23. will prevent too great movement oftheextension bars 17. o

in Figs. 1 and 2, a fastening means adapted for employment upon the skates intended for the use of women and children is disclosed, and in this arrangement, the toe fastening is of the usual clamp form adapted for such change, the clamp members 28 and 29 being simultaneously adjusted and brought to a. bearing relation against the soleof the shoe by turning the clamp screw wrench or other suitable means. The heel plate 13 has upturned limbs or cars ,81 provided around the outer extent thereof and a metal heel band 32 is'secured-to these ears by rivets 33 to form a rigidstruo .ture with the heel plate, a felt, leather, or

other protective lining 34: being secured 1H.

place within the heel band 32oto'protect the heelv of the shoe from the wear of the metal. A buckle 35 is secured to one side of the heel band 32 by a metal band 36 which is riveted in place, and a strap or other flexible member 87 is secured to the opposite side of the heel band 32 to be received across the instep of the wearer and to have the tongue of the buckle penetrated through one of the openings 38 thereof to procure the proper tension across the foot.

In the use of the skate and in fitting the same to the foot, the nut 26 on the end of the bolt 23 is loosened to release the bearing tension exerted by the head of the bolt and by the washer 25, and the heel member 9 and the toe member 8 may then be adproper position beneath the ball of the foot '46 to accomplish the proper poise over the front wheels 7 mounted on the axle. When the desired adjustment has been obtained, the nut 26 will be again tightened against the washer 25 and the head of the bolt 23' willcome'into bearing engagefment with the top of theclip 21 which will cause the side extension 22 thereof to exert a bearing pressure against the flanges 18 of the extension plates 16 and will bring these flanges to a frictional bearing contact against the flanges 19: of the extension plates 17 and will sestep of'the foot and the buckle 35 has the tongue passed through one of the openings 38 to hold the shoe properly positioned within the heel band 32. The toe clamp members 28 and 29 are tightened against the side edgesof the sole' of the shoe in the manner as hereinbefore' -set forth, and the skate is positioned and securely held in the proper relation.

From the foregoing, it will be seen that I have provided a skate having heel and toe portions by which the wheel-carrying trucks are held in the proper relation, which members are freely adjustable. Further, it will be seen that the connection between the heel and toe portions of the skate is in the nature of an angle-iron truss structure in which the one member gives support to and receives strength from the remaining mom-- bersand that there is very little possibility of the extension structure between the members of the skate becoming bentor otherwise disalined.

While I have herein shown and described only specific. forms and adaptations of the invention, it will be understood that slight changes might be made in: the form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not wish to be limited thereto except for such limitations as the claims may import.

I claim l. A skate comprisingheel and toe portions, a pair of spaced-apart extension plates having outwardly extending flanges carried at the lower'edges thereof arranged to project from the heel portion in a' forward direction, a pair oflike flanged plates carried by the toe portion in a spaced-apart relation to be interfitted with the extension plates of the 'heel portion, and means to bear I against said extension plates and the flanges thereof to secure the same in" a rigid ad justed relation and to prevent longitudinal shifting of the one pair with respect to the remaining plates.
